Adhesive resins and method of production thereof

Abstract

An adhesive resin comprising the polymer of dimethyl-di-(cyclohexen-3)-yl-methane as well as a copolymer of this compound with at least one mono-or di- ethylenically unsaturated hydrocarbon or chlorinated hydrocarbon, said hydrocarbon having 4 to 12 carbon atoms. A method of making these resins and a method of causing adhesion using such resins are also disclosed, as well as compositions including this resin.

What is claimed is: 
     
       1. A resin comprising a polymer of the monomer dimethyl-di-(cyclohexen-3)-yl-methane having a softening point in the range of about 70° to 150° C. and a number average molecular weight of about 800 to about 1200. 
     
     
       2. A resin according to claim 1 further comprising as a comonomer at least one mono- or di-ethylenically unsaturated hydrocarbon or chlorinated hydrocarbon, said hydrocarbon having from 4 to 12 carbon atoms, wherein the molar ratio of dimethyl-di-(cyclohexen-3)-yl-methane to said hydrocarbon is at least 1 to 2. 
     
     
       3. A resin according to claim 2 wherein said comonomer is taken from the class consisting of alpha-pinene, beta-pinene, iosprene, dipentene, vinyl cyclohexene, cyclododecene, styrene, methyl-derivatives of styrene selected from the group of α-methyl styrene, para-methyl styrene and ortho-methyl styrene, cyclopentadiene, dicyclopentadiene, butadiene and chloroprene. 
     
     
       4. A resin according to claim 2 wherein said comonomer is taken from the class consisting of alpha-pinene, beta-pinene, isoprene, dipentene, vinyl cyclohexene, cyclododecene, styrene, cyclopentadiene, butadiene and chloroprene. 
     
     
       5. A resin according to claim 2 wherein said ratio is at least 1 to 1. 
     
     
       6. A resin according to claim 5 wherein said ratio is from 1:0.1 to 1:1. 
     
     
       7. A resin according to claim 4 wherein said comonomer is alpha-pinene, beta-pinene, dipentene, cyclopentadiene, vinyl cyclohexene, cyclododecene, or styrene. 
     
     
       8. A resin according to claim 4 wherein said comonomer is butadiene, isoprene or chloroprene.
